I was assuming you read the article before generating this answer, but apparently you haven't. Rufinius is mentioned in the third, fourth, and fifth paragraphs of this article. You might want to read that before further resisting Scriptural truths that are as yet above your knowledge base.
I believe scripture is quite clear in the separation between soul and body, separated upon bodily death and ultimately reunited at the end of time.
The Gospels are quite clear that Jesus' spirit was placed into the hands of The Father, that His body was placed in the new grave tomb of Joseph of Arimethea, and that Jesus soul went to Paradise, otherwise known as Abraham's bosom, together with that of the malefactor to whom He promised fellowship that very day.
If you can grasp this, you know more than the person who wrote the article.
Scripture is difficult enough to piece together without coming up with wild theories and otherwise piecing together completely unrelated passages and topics.
I admit, I supplied very little guidance as to how to interpret the diagram of the dispostion of souls at different historical times. But the purpose was to show a substantial difference between the Bible account of Christ's death and that of the author of the article.
With a little luck, study, wise counsel, and foresight you can avoid giving opinions like this that have no basis.
But thanks for your attention. I hope this will give you an encouragement to do your own research on the disposition of a person's components at death, as well as (for some) a second death.
Here is the source of a carefully prepared paper on the topic:

Read it through, and you'll be wiser than your pastor.
I read the article a couple days before that comment and had forgotten that Rufinius was a scholar. I thought you were referring to someone on FR who was posting comments. My mistake.
